Purpose: To investigate factors related to cardio-cerebrovascular disease and groups disadvantaged by it in Korean middle-aged women, using the Korea National Health and Nutrition Examination Survey (KNHANES). Methods: The present study was conducted with 1,627 middle-aged women, aged 40 to 64 years, who participated in the 7th (2016) Korea National Health and Nutrition Examination Survey conducted by the Korea Centers for Disease Control and Prevention. Results: Cardio-cerebrovascular disease among middle-aged women was associated with quality of life, menopause, diabetes mellitus, body mass index, and family history of hypertension. The incidence of cardio-cerebrovascular disease in middle-aged women was found to be the most prevalent in women who have entered menopause, have a family history of hypertension, and have a body mass index greater than $30.0kg/m^2$. Conclusion: This study classifies the subjects according to the risk level of each disadvantaged group for cardio-cerebrovascular disease prevention and management in middle-aged women. The results provide evidence to support a tailored cardio-cerebrovascular disease prevention and management program based on the related factors of disadvantaged groups and to establish strategies in educational and practical aspects.

Objectives : AMH (Anti-Müllerian Hormone) is considered a sensitive marker of ovarian reserve, and it tends to be included among basic fertility tests. This paper is to report four pregnancies which were achieved by subfertile women with low AMH level after Korean medical treatments. Methods : Four cases of pregnancy by subfertile women, aged 34 to 37, with low AMH level (0.04 to 0.76 ng/mL), after Korean medical treatments between July 2012 and May 2015, were analysed. The patients were diagnosed as Kidney deficiency (腎虛), Blood extravasation (瘀血) and/or Liver Qi stagnation (肝氣 鬱結). Herbal medicine, acupuncture, pharmacopuncture and moxibustion treatments were applied. Results : The four subfertile women with low AMH level achieved pregnancy after Korean medical treatments. Conclusions : The case report suggests that Korean medical treatment can be an effective option for subfertile women with low AMH level before Assisted Reproductive Technology.

본 연구는 미국 Utah주의 Logan시에 있는 유타주립대하(USU)Credit Union의 멤버들을 대상으로, 신용사용과 신용에 대한 태도가 그들의 경제적 만족도와 어느정도 관련이 있는지를 조사하였다. 연구는 1989년 3월에서 5월까지 걸쳐 USU Credit Union의 지원으로 이루어졌으며, 자료는 21세에서 65세까지의 멤버들 중 500명을 임의 추출하여 설문지 조사를 실시하여(설문지는 본 연구를 위한 문항과 Credit Union 멤버 Survey문항이 함께 이루어졌다) 그중 274명(54.8%)으 답변이 자료분석에 사용되었다. 대부분의 사람들은 집이나 차, 또는 교육비, 의료비에 신용을 사용하는데 긍정적 태도를 보였으며, 반수 이상의 사람들이 신용을 사용함으로써 수수료 또는 이자를 지불하고 있었다. 월평균 신용 납부액은 $643이였으며, 반수 이상의 응답자가 그들의 신용차입액에 대해 걱정하고 있는 반면, 4.4%의 응답자만이 신용을 사용하지 않고 있다고 대답했다. t-테스트, 변량분석, 그리고 상관관계 분석에 의해 경제적 만족도와 의미있는 관계를 가지고 있는 요인들이 단계별 다중 희귀분석에 이용되었는데, 그 결과 사람들의 신용부담액에 대한 근심도가 그 어느것보다도 경제적 만족도와 강하게 연관되어 있는 것으로 나타났다. 이는 과거의 조사들이 가정의 빚, 즉 신용부담액과 수입에 대한 비율로써 가정의 경제적 만족정도(financial well-being)를 측정해온 것에 반한 사실로서, 경제적 만족도는 개인의 주관적 측정인 신용부담액에 대한 근심도와 큰 관련이 있음을 보여주었다.

Let ${\kappa}$ be a positive integer and let G be a simple graph with vertex set V(G). A function f : V (G) ${\rightarrow}$ {-1, 1} is called a signed total ${\kappa}$-dominating function if ${\sum}_{u{\in}N({\upsilon})}f(u){\geq}{\kappa}$ for each vertex ${\upsilon}{\in}V(G)$. A set ${f_1,f_2,{\ldots},f_d}$ of signed total ${\kappa}$-dominating functions of G with the property that ${\sum}^d_{i=1}f_i({\upsilon}){\leq}1$ for each ${\upsilon}{\in}V(G)$, is called a signed total ${\kappa}$-dominating family (of functions) of G. The maximum number of functions in a signed total ${\kappa}$-dominating family of G is the signed total k-domatic number of G, denoted by $d^t_{kS}$(G). In this note we initiate the study of the signed total k-domatic numbers of graphs and present some sharp upper bounds for this parameter. We also determine the signed total signed total ${\kappa}$-domatic numbers of complete graphs and complete bipartite graphs.

The purpose of this study was to find out the relationship between the conspicuous consumption of clothing and status inconsistency. For this study, two kinds of guestionnaires were conducted to collect data for the conspicuous consumption variables of clothing and status inconsistency variables. Status inconsistency was measured by educational levels and occupational levels of married women and their husbands, the family′s total income. Status inconsistency was defined by the inconsistency among married women′s and their husband′s educational levels, family′s total income, their husband′s occupational levels. In order to investigate status inconsistency effects, when their investment (education0 are lower than their rewards (income or occupation) they are classified as over-rewarded inconsistency, while their investments is higher than their rewards, as under-rewarded inconsistency, and their investments are equal to their rewards, as consistency. The conspicuous consumption variables in clothing were consisted of seven variables; Brand-oriented, Fashion-oriented, Leisure-showing, Leisure-oriented purchase of clothing and Excessive expenditure to purchase of clothing, purchase of Imitation clothing in well-known brand and purchase of Expensive clothing from abroad. Data were obtained fro m436 housewives living in Kwang-ju are a and analyzed by F-test, Pearson′s Correlation and Frequency. The results of this study were follow; When the subjects were divided into three group according to their status inconsistency type, there were significant differences (P<.05 or P<.01) among groups of conspicuous consumption variables in clothing. The groups of "under pivileged" status inconsistency type and "over rewarded" status inconsistency type were tend to show conspicuous consumption in clothing than other type of status inconsistency groups.

Endogenous retroviruses (ERVs) have been integrated into vertebrate genomes and have momentously affected host organisms. Horses (Equus caballus) have been domesticated and selected for elite racing ability over centuries. ERVs played an important role in the evolutionary diversification of the horse genome. In the present study, we identified six equine ERV families (EqERVs-E1, I1, M2, P1, S1, and Y4), their full-length viral open reading frames (ORFs), and elucidated their phylogenetic relationships. The divergence time of EqERV families assuming an evolutionary rate of 0.2%/Myr indicated that EqERV-S3 (75.4 million years ago; mya) on chromosome 10 is an old EqERV family and EqERV-P5 (1.2 Mya) on chromosome 12 is a young member. During the evolutionary diversification of horses, the EqERV-I family diverged 1.7 Mya to 38.7 Mya. Reverse transcription quantitative real-time PCR (RT-qPCR) amplification of EqERV pol genes showed greater expression in the cerebellum of the Jeju horse than the Thoroughbred horse. These results could contribute further dynamic studies for horse genome in relation to EqERV gene function.

This study examined the satisfaction level and effects of after-school program cooking activities in children of multicultural families. A total of 135 children of general and multicultural families from 3th to 6th grades and their 11 teachers were surveyed, and 75 multicultural family children underwent a cooking activity program. Children of multicultural families showed higher participation in cooking activities than other Korean children. Children of multicultural families wanted to be involved in cooking activity programs after school more than other Korean children. These children also showed a higher rate of wanting to cook Korean foods compared to children of general families. Regarding reasons for participating in cooking activities, 'I think I'm glad to be served delicious food' response was the most common. Children of multicultural families showed higher participation in cooking activities than children of general families. Regarding school life changes, children of multicultural families were found to be less picky of foods in general as well as kimchi and vegetables. In conclusion, cooking activity programs for children of multicultural family showed beneficial effects on diet and understanding of Korean culture.

In this paper, we consider a single-manufacturer single-buyer supply chain problem where a single manufacturer purchases and processes raw materials into a family of items in order to deliver a family of items to a single buyer at a fixed interval of time for effective implementation of Just-In-Time Purchasing. An integrated multi-item lot-splitting model of facilitating multiple shipments in small lots between buyer and manufacturer is developed in a JIT Purchasing environment. Previous research on the integrated model assumed that the manufacturer orders raw materials m (integer) times for every production run (lot multiplier policy for the raw material). In this paper, we consider a generalized policy in the replenishment of raw materials, allowing lot multiplier policy and lot splitting policy. An iterative solution procedure is developed to find the order interval for finished goods and raw materials, and number of shipments between buyer and manufacturer. We show by numerical example that when the integrated policy is adopted by both buyer and manufacturer in a cooperative manner, both parties can benefit.

The syndecan family consists of four transmembrane heparan sulfate proteoglycans present in most cell types and each syndecan shares a common structure containing a heparan sulfate modified extracellular domain, a single transmembrane domain and a C-terminal cytoplasmic domain. To get a better understanding of the mechanism and function of syndecan-4 which is one of the syndecan family, it is crucial to investigate its three-dimensional structure. Unfortunately, it is difficult to prepare the peptide because it is membrane-bound protein that transverses the lipid bilayer of the cell membrane. Here, we optimize the expression, purification, and characterization of transmembrane, cytoplasmic and short extracellular domains of syndecan4 (syndecan-4 eTC). Syndecan-4 eTC was successfully obtained with high purity and yield from the M9 medium. The structural information of syndecan-4 eTC was investigated by MALDI-TOF mass (MS) spectrometry, circular dichroism (CD) spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy. It was confirmed that syndecan-4 eTC had an ${\alpha}$-helical multimeric structure like transmembrane domain of syndecan-4 (syndecan-4 TM) in membrane environments.

An extracellular xylanase was purified to homogeneity by sequential chromatography of Fomitopsis pinicola culture supernatants on a DEAE-Sepharose column, a gel filtration column, and then on a MonoQ column with fast protein liquid chromatography. The relative molecular mass of the F. pinicola xylanase was determined to be 58 kDa by sodium dodecyl sulfate polyacrylamide gel electrophoresis and by size-exclusion chromatography, indicating that the enzyme is a monomer. The hydrolytic activity of the xylanase had a pH optimum of 4.5 and a temperature optimum of $70^{\circ}C$. The enzyme showed a $t_{1/2}$ value of 33 h at $70^{\circ}C$ and catalytic efficiency ($k_{cat}=77.4\;s^{-1}$, $k_{cat}/K_m$=22.7 mg/ml/s) for oatspelt xylan. Its internal amino acid sequences showed a significant homology with hydrolases from glycoside hydrolase (GH) family 10, indicating that the F. pinicola xylanase is a member of GH family 10.
